I ordered two Kits and trying to get a good Signal in Kenya.
Satellite position is perfect for me - 76 degrees elevation - pointing nearly vertically up.
Although I cannot get any usable signal, neither without nor with the LNA Board which came with the Kit.
I tried both Kits, both behave exactly the same - therefore Hardware fault is pretty much impossible.

I am wondering whether the LNA needs Power?
It has a Power-LED and 5V Pins - but in my setup the LED stay off (not getting powered by the SDR?)

Also - wondering if the Outernet Software enables DC on the LNA - rtl_biast brings a error…?

I would expect at least 7dB SNR where I am - but getting just 1.5dB.
It pretty much looks like I have the same issue as many other people here…

Could that be a LNA issue of not being powered?

Addition:
Have installed the Panel Antenna on a 1.2m Satellite Dish (replacing the Dish-LNB with Outernets PanelAntenna), pointing to 25E. (Results in Azimuth 276° and Elevation 76° for my Location in Nairobi)
Tried with and without LNA. Without lna 2-2.5dB SNR, with LNA 1-1-5dB.
In my opinion the LNA are not getting powered. (I tried both LNA’s I got sent)

I presume when you say “kit” you mean the antenna, LNA and dongle only? Are you not using the CHIP?

The newer RTL-SDR dongle supplied with my Outernet kit uses a software switch to turn on the bias tee voltage to feed the LNA. The CHIP is already configured with the piece of code to turn on the bias tee.

It appears your RPi image attempts to load and execute that code but failed for some reason. The code is available on the RTL-SDR site. It has to run every time the device boots or there will be no voltage supplied to the LNA.

Other RTL dongles have simply a solder jumper pad to physically turn it on. That may be why the other dongle worked.
